Preparing for hybrid mode:
- create vE820 for pre-launched VMs and do other init code when the
vm_config->type is PRE_LAUNCHED_VM.
- create ve820.c for each board because without wrapping by
CONFIG_PARTITION_MODE, ve820_entry[] needs to be visible even when
compiling target boards that haven't enabled pre-launched VMs.
- remove create_prelaunched_vm_e820() from vm.c and implement board
specific function for each $(CONFIG_BOARD)/ve820.c. The reasons being:
- don't need to define ve820_entry[32] for those boards that don't
support pre-launched VMs.
- more importantly, this makes it much easier to create different per-VM
vE820 when it's needed.
